Description

TECHNICAL FIELD

[0001] The present application relates to the field of audio processing equipment, in particular to a live broadcast sound card. BACKGROUND

[0002] In recent years, with the rapid development of the live broadcast industry, the diversification and functional optimization of live broadcast equipment have become key factors to improve the quality of live broadcast and user experience. As an indispensable audio processing device in the live broadcast process, the live broadcast sound card undertakes functions such as sound effect adjustment, mixing, noise reduction, and sound effect addition. However, the structural design of traditional live broadcast sound cards has many problems, which limits the operation experience in the live broadcast process.

[0003] The live broadcast sound cards currently on the market usually adopt a fixed structure, and all the keys and knobs are centrally arranged on the device host. Since the sound card is usually placed on one side of the live broadcast equipment (such as a mobile phone, a video camera, a computer, etc.) or on the desktop, the host needs to shift his gaze or even move his hand away from the live broadcast equipment to adjust the keys or knobs when operating the sound card, causing the live broadcast picture to be unstable and affecting the live broadcast effect.

[0004] At the same time, the number of keys on the traditional live broadcast sound card is large, but the classification is not clear enough, and the key spacing is small, so the process of finding and operating the keys during the live broadcast process is relatively cumbersome, reducing the smoothness of the live broadcast.

[0005] In order to solve the above problems, some existing technologies propose a split type or wireless control scheme, such as a wireless control module connected through Bluetooth or Wi-Fi, so that the key module can be installed separately in a position within the host's reach. However, the wireless control method has a certain delay and is easily disturbed by the external environment, causing unstable signals. At the same time, the independent wireless control module needs additional power supply and pairing operation, increasing the complexity of the equipment, and is not convenient in the actual live broadcast scene.

[0006] In addition, the installation method of the existing live broadcast sound card mostly needs an additional bracket to fix the live broadcast equipment, causing the live broadcast sound card and the live broadcast equipment to occupy two different space positions, so that the host needs to frequently switch operations, affecting the overall smoothness of the live broadcast.

[0007] Finally, in the traditional live broadcast sound card, the knobs and keys are used to adjust sound effect parameters such as volume, reverb, equalization, etc. However, since the knobs and keys are mechanical, if they are not reset after the live broadcast is over, they may cause the following problems when used next time:

[0008] When different hosts use the same equipment, if the knobs and keys are not reset, the next user may unknowingly use the wrong parameters directly, affecting the live broadcast sound effect, so the knobs and keys need to be manually rotated to the reset state after each use, but this operation is sometimes forgotten. SUMMARY

[0009] In order to solve the above problems, the present application provides a live sound card, which overcomes the shortcomings of the prior art in operation convenience, device storage and long-term use stability, and improves the smoothness of live operation and use experience.

[0013] As a preferred technical scheme, each control key comprises a key cap, a key rod and a sealing part, the key cap is connected with one end of the key rod, the other end of the key rod is in contact with the key element on the key plate, the sealing part is located between the key cap and the fixed shell, the sealing part is used for sealing a shaft hole formed in the fixed shell, the key rod passes through the shaft hole, and the shaft hole has a larger diameter than the key rod.

[0014] As a preferred technical scheme, each clamping opening is further provided with an elastic guide connecting plate, one end of the elastic guide connecting plate is connected with the opening side of the clamping opening of the fixed shell, and the other end is a movable end.

[0015] The key plate and the key shell are fixedly installed on the elastic guide connecting plate, and each elastic guide connecting plate is provided with an inclined guide surface at the insertion end of the live device, the elastic guide connecting plate is elastically extruded when the live device is inserted into the clamping opening, and the control key is extended to the outside of the fixed shell.

[0016] As a preferred technical scheme, the bottom of each of the two key modules is provided with a mounting protrusion, a key wheel mounting groove is formed in the mounting protrusion, a rotary knob is embedded in the mounting protrusion, the rotary knob is conductively connected to the key plate at the corresponding position through a flexible flat cable, and a key roller is mounted on the rotary knob of the rotary knob.

[0017] As a preferred technical scheme, a support pad is further arranged at the bottom of the key module when the folding and extending support is pulled out, the support pad is provided with a guide support portion protruding therefrom, the guide support portion is provided with an arc-shaped positioning groove in the middle, the key roller is supported in the arc-shaped positioning groove, and the two ends of the guide support portion are arc-shaped guide surfaces for resetting the rotary knob when the folding and extending support is reset.

[0018] As a preferred technical scheme, each of the folding and extending supports comprises a first connecting shaft, the first connecting shaft is rotatably connected to the device host, a first hinged support is rotatably arranged on the first connecting shaft, the first hinged support is telescopically inserted into a second hinged support, and a third hinged support is hingedly arranged on the second hinged support.

[0019] The second connecting shaft is rotatably connected to the fixed shell, the third hinged support is rotatably connected to the second connecting shaft, and the first connecting shaft, the first hinged support, the second hinged support, the third hinged support and the second connecting shaft are provided with wiring holes.

[0020] As a preferred technical scheme, each of the key modules is connected to the control mainboard in the device host through the wiring holes in the folding and extending supports.

[0021] As a preferred technical scheme, the bottom of the device host is further provided with a base, the base is provided with a hinged block, and the device host is hingedly connected to the hinged block.

[0022] As a preferred technical scheme, the four corners of the device host are provided with mounting grooves, and the folding and extending supports are accommodated in the mounting grooves when the folding and extending supports are folded.

[0023] The folding and extending supports are adopted in the present application, so that the live broadcast device can be directly fixed on the live broadcast sound card without the need for additional support, thereby reducing the occupied space of the device, forming an integrated design of the live broadcast device and the live broadcast sound card, and avoiding the problems of inconvenience and frequent switching caused by the separation of traditional devices.

[0024] The split button control structure separates the control buttons on the traditional live streaming sound card from the host and places them in the four corners of the live streaming device. This allows the broadcaster to operate the device directly without taking their eyes off it during the live stream, improving operating efficiency and reducing the impact on the live stream by searching for buttons. Because the buttons are distributed, they can be quickly located when operating the device, solving the problem of inconvenience caused by concentrated buttons.

[0025] This invention incorporates an elastic guide connecting plate and an inclined guide surface within the button module. When a live streaming device is inserted, it automatically positions itself and presses against the guide plate, causing the originally retracted control buttons to protrude and become operational. After the live streaming device is removed, the elastic guide connecting plate returns to its original position with the control buttons intact. The sealing part then seals the shaft hole, ensuring that the control buttons retract when not in use and cannot be pressed down. This effectively protects the control buttons, increases the waterproofness of the button area, and prevents damage caused by accidental squeezing during transport.

[0026] This invention places the knob at the bottom as a rolling support during the reset process of the folding extension bracket. After the folding extension bracket is reset, the knob can be reset for convenient use next time. Attached Figure Description

DETAILED DESCRIPTION

[0036] All features disclosed in this specification, and / or all steps of any methods or processes disclosed in this specification, can be combined in any manner, except where features or steps are mutually exclusive.

[0037] Any feature disclosed in this specification, unless stated otherwise, can be replaced by alternative features serving the same, equivalent or similar purpose.

[0038] As shown in Figure 1 and Figure 2 A live streaming sound card according to the present application includes a device host 1, a folding extension support 3 is arranged at each corner of the device host 1, and four folding extension supports 3 can be stretched and adjusted in angle relative to the device host 1. According to the size of a live streaming device 6, the position of the folding extension support 3 is adjusted, and the clamping of different live streaming devices 6 is completed.

[0039] In this embodiment, four key modules 4 are further included and are respectively mounted on the folding extension supports 3. Each key module 4 is provided with a clamping opening 11, and a device mounting groove is formed between the four key modules 4. The live streaming device 6 is mounted in the clamping opening, the device host 1 is controlled by the key modules 4, the four key modules 4 are arranged at the four corners of the front end of the live streaming device 6, and the key operation can be performed without leaving the picture of the live streaming device 6 during live streaming, which does not affect the live streaming effect. Since the key modules 4 are arranged separately, the gap between the keys is enlarged, which facilitates the search and operation of the keys during live streaming. The keys of the present application are separated from the device host 1 and are used as clamping positioning members for clamping the live streaming device 6. The live streaming device 6 can be fixed and maintained at the required live streaming angle, and the keys can be used for control. The keys are arranged at the four corners of the live streaming device 6, and the sound card operation and live streaming can be performed without leaving the line of sight during live streaming.

[0040] As Figure 2 And Figure 3 As shown in the figure, each key module 4 includes a fixed housing 43, the clamping opening 11 is arranged on the fixed housing 43, each clamping opening 11 is provided with a key plate, and each key plate is externally wrapped with a key shell 42. The key plate is provided with control keys 5 of different functions, and each control key 5 is located at the outer side end of the fixed housing 43. The control key 5 is arranged opposite to the key element on the key plate. The key plate is divided into four separate parts, and the control keys 5 of different functions are arranged on different key plates. Therefore, during live broadcast, the live broadcast sound card does not need to be operated, and the live broadcast equipment 6 can be operated at the four corners, and the line of sight does not need to be away from the live broadcast equipment 6.

[0041] Continuing to refer to Figure 3 Each control key 5 includes a key cap 44, a key rod, and a sealing part 45. The key cap 44 is connected to one end of the key rod, the other end of the key rod is in contact with the key element on the key plate, the sealing part 45 is located between the key cap 44 and the fixed housing 43, the sealing part 45 is used to seal the shaft hole arranged on the fixed housing 43, the key rod passes through the shaft hole, and the shaft hole has a larger diameter than the key rod. Each clamping opening 11 is also provided with an elastic guide connecting plate 41. One end of the elastic guide connecting plate 41 is connected to the opening side of the clamping opening 11 of the fixed housing 43, and the other end is a movable end.

[0042] The key plate and the key shell 42 are fixedly installed on the elastic guide connecting plate 41, and each elastic guide connecting plate 41 is provided with an inclined guide surface 46 at the insertion end of the live broadcast equipment 6. When the live broadcast equipment 6 is inserted into the clamping opening 11, the elastic guide connecting plate 41 is elastically extruded, and the control key 5 is extended to the outside of the fixed housing 43.

[0043] Through the elastic guide connecting plate 41, when the live broadcast equipment 6 is not clamped, the elastic guide connecting plate 41 is elastically reset, the key plate and the control key 5 are retracted, and the sealing part 45 seals the shaft hole. At this time, because the control key 5 is retracted, external force cannot press the key, and the sealing part 45 seals the shaft hole, achieving the purpose of sealing the shaft hole and increasing the protection of the control key 5 when the sound card is not used. Because the elastic guide connecting plate 41 is arranged, when the live broadcast equipment 6 is inserted into the clamping opening 11, the elastic guide connecting plate 41 is elastically extruded, the elastic rebound force is used to press the live broadcast equipment 6, preventing loosening, and the clamping assembly is more stable.

[0044] As Figure 5As shown, the bottom of the two bottom button modules 4 is provided with a mounting protrusion 10, a key wheel mounting groove is formed in the mounting protrusion 10, and a rotary knob button 92 is embedded in the mounting protrusion 10. The rotary knob button 92 is conductively connected to the corresponding button plate through a flexible flat cable. A button roller 91 is mounted on the rotary knob button 92. The button roller 91 is located in the key wheel mounting groove and extends outward.

[0045] The function of the rotary knob button 92 is selected, and the rotary knob button 92 that needs to be set at the specified position is arranged on the mounting protrusion 10 and in rolling contact with the external desktop. In this embodiment, one rotary knob button 92 is arranged on each side, i.e., a total of two rotary knob buttons 92 on the left and right sides as rolling supports. Therefore, it is best to select two rotary knob buttons 92 that need to match two functions, such as the background music volume knob and the microphone volume. If the microphone volume is increased, the background music volume may need to be lowered simultaneously to prevent the host's voice from being too loud and causing discomfort to the audience. Conversely, if the microphone volume is lowered, the background music volume may need to be increased simultaneously to maintain the fullness of the live sound. Therefore, it is a good choice to arrange two rotary knob buttons 92 as rolling supports at the bottom. In this way, we only need to slightly push the live streaming device 6 during live streaming, and a large displacement distance is not required, so that the adjustment of the two rotary knob buttons 92 can be performed simultaneously, which is very convenient. In this way, we do not use a support pad 8, and the parameter adjustment at the rotary knob position can be completed by slightly pushing the folding and extending support 3.

[0046] A support pad 8 is further included. When the folding and extending support 3 is pulled out, the support pad 8 is arranged at the bottom of the button module 4. The support pad 8 is provided with a guide support portion 7. The guide support portion 7 has an arc-shaped positioning groove 81 in the middle. The button roller 91 is supported in the arc-shaped positioning groove 81. The two ends of the guide support portion 7 are arc-shaped guide surfaces. When the folding and extending support 3 is reset, the rotary knob button 92 is reset. When the rotary knob button 92 at the bottom is arranged as a function rotary knob button 92 that does not need to be adjusted frequently, we only need to adjust it to the best position during live streaming debugging, and then install the support pad 8 and use the guide support portion 7 to position the rotary knob button 92, thereby increasing the stability of use. Therefore, the support pad 8 is an optional component that can be used or not used as needed.

[0047] When the folding and extending support 3 is reset, the rotary knob button 92 is kept in rolling support with the desktop. The live streaming device 6 is removed, and the folding and extending support 3 is pushed to continuously shrink. The upper folding and extending support 3 can be pushed first, and then the lower folding and extending support 3 can be pushed. At this time, the rotary knob button 92 and the folding and extending support 3 can be reset by using the pushing force.

[0048] As Figure 6 shown in the figure, the folding and stretching support 3 comprises a first connecting pivot 31, which is rotationally connected with the device host 1, a first hinged support 32 is rotationally arranged on the first connecting pivot 31, the first hinged support 32 is telescopically inserted into a second hinged support 33, and a third hinged support 34 is hingedly arranged on the second hinged support 33.

[0049] Further, a second connecting pivot 35 is rotationally connected with the fixed shell 43, the third hinged support 34 is rotationally connected with the second connecting pivot 35, and the first connecting pivot 31, the first hinged support 32, the second hinged support 33, the third hinged support 34 and the second connecting pivot 35 are internally provided with wiring holes. The hinged and rotational positions can be sleeved with a rubber damping sleeve to increase the damping property, so that the folding and stretching support 3 can better maintain the position after stretching.

[0050] Each of the key modules 4 is connected with the control mainboard in the device host 1 through the wiring hole in the folding and stretching support 3.

[0051] As Figure 4 shown in the figure, the bottom of the device host 1 is further provided with a base 13, the base 13 is provided with a hinged block 12, and the device host 1 is hingedly connected with the hinged block 12. The hinged position can also be provided with a rubber damping sleeve, so that the device host 1 can adjust the angle relative to the base 13 and maintain the position.

[0052] Further, the device host 1 is provided with mounting slots 2 at the positions of four corners, the folding and stretching support 3 is accommodated in the mounting slots 2 when folded, the folding and stretching support 3 is pulled out when used, and the folding and stretching support 3 is accommodated in the mounting slots 2 after use.

[0053] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements without creative labor are covered within the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
